SNMP Overview

The Simple Network Management Protocol (SNMP) system consists of the following three parts:
•
•
•
SNMP is an application-layer protocol that provides a message format for communication between
SNMP managers and agents.
The SNMP manager can be part of a Network Management System (NMS) such as CiscoWorks. The
agent and MIB reside on the ATM switch router. To configure SNMP on the ATM switch router, you
define the relationship between the manager and the agent.
The SNMP agent contains MIB variables whose values the SNMP manager can request or change. A
manager can get a value from an agent or store a value into that agent. The agent gathers data from the
MIB, the repository for information about device parameters and network data. The agent can also
respond to a manager's requests to get or set data.
An agent can send unsolicited traps to the manager. Traps are messages alerting the SNMP manager to
a condition on the network. Traps can indicate improper user authentication, restarts, link status (up or
down), closing of a TCP connection, loss of connection to a neighbor router, ATM switch router, or other
significant events.
